Chemstation Peak Identification if Outside RT Window
Posted: Thu Dec 10, 2015 5:36 pm
Hello, I'm a new participant here. I have lots of GC and IC experience and have just started working with HPLC systems.
In TotalChrom and Chromeleon if a peak in a single data file is slightly outside the retention time window it is easy to assign it as one of the calibrated analytes in the method and subsequently integrate and report without updating the method.
I'm using a system with OpenLab Chemstation software and I don't seem to be able to assign an identity to a peak if it falls outside an RT window.
I've enlarged the method RT windows slightly to rectify the problem but I'm curious if it can it be done as part of reprocessing or recalculating?
Thanks,
Mike
